drain and CMOS output (active “H” and “L”), both of which have va
product lineups. This series features much lower current consum
and higher detection voltage accuracy than the S-805 Series. S
miniature package is added for the S-807 Series, the S-807X
Series. This small SOT-23-5 style package allows the design
shrink the size of his finished product. Electrical specs for th
807XXSX Series are the same as the standard S-807 Series. O
forms of the S-807XXSX Series are Nch open-drain and CMOS a
“L”.

The last digit of the model name changes depending upon the packing form when it is an SOT package product (S-807
Series is packed on tape).
S : Stick
T : Tape (T1 and T2 types are available depending on the direction of detectors on the tape.)
** Please ask our sales person if you need another detection voltage product.
